To Garmin, or not to Garmin

Toying with the idea of  rationalizing this purchase investing in a running watch GPS thing-a-ma-bob. While MapMyRun has been my faithful FREE running companion (via app on my Blackberry) since the beginning of time, it is becoming increasingly bulky to hold my phone whilst running - a.) it gets sweaty, b.) when it rains and you get stuck in said rain, your phone dies and you freak out. 

Garmin just came out with a new watch - retailing $129.99. The reviews/inquiries/incessant questions to anyone that will listen thus far have been positive, it appears to be super easy to use, and connects online so you can store your workouts. Excuse my sticker shot but let's be honest, this watch won't give me rock hard abs, nor will it make me run faster. Ahhh, what should I do???

Garmin Forerunner 10

Attempting to be cognizant of the fact I am unsure of how far my running journey will take me, I also need an alternative to what I'm doing now cuz they ain't no way in the fiery inferno below I'm holding anything for 13.1 miles. Ain't happening. 

What running device do you use?
